Shipping Details

Star Tron enzyme fuel treatment is a multifunctional fuel additive which uses a unique enzyme technology that allows all engines to start easily and run smoothly, even when using ethanol-blended fuel or after sitting idle for months. Star Tron allows fuel to burn more completely, which results in maximum performance, fuel efficiency and reliable operation. Star Tron will stabilize fuel for up to two years, preventing the formation of gums and other solids that clog carburetors and fuel injectors. Star Tron helps prevent phase separation by dispersing water throughout fuel as submicron-sized droplets that can be safely eliminated while the engine operates. Star Tron Small Engine formula is ideal for use in all gas engines including; boats, cars, trucks, motorcycles, small equipment as well as engines that use pre-mix fuel.

Star Tron is the best for me.

Would Recommend

The product is perfect for my requirements. and each bottle was shipped in a sealed plastic bag. However, 2 of the containers had loose caps, so some fluid leaked. next time check to ensure the containers are caps are tight and properly sealed to prevent leaks.

Great product

Would Recommend

I have been using Star Tron for about ten years. Use it in my motorcycles, lawn tractor, generator, snowblower and more. All of these are over ten years old and never rebuilt or replaced a carburetor. All have started right up after sitting up to a year at a time.
